A.W. Tozer emphasizes the importance of repentance through the example of Peter, who, despite his faults, demonstrated a profound ability to grieve for his sins against Christ. Tozer suggests that this capacity for genuine repentance is a rare and valuable treasure that can lead to purity and power in our lives. He warns against using the faults of saints as a shield for our own unconfessed sins, urging us to let our weaknesses drive us closer to God. The sermon encourages believers to learn from Peter's journey, recognizing that his life serves as a model for transformation through repentance. Ultimately, Tozer expresses gratitude for Peter's life and the lessons it offers to those willing to embrace their own shortcomings.

For all his faults, or perhaps because of them, Peter could do one thing superbly: he could shed tears of grief when he had offended his Savior. The ability to repent is a sweet treasure, and one that is rare among us these days. If we had Peter's penitent heart, we might go on to have his purity and his power. Should the contemplation of Peter's faults give aid and comfort to an impenitent heart, then that heart has only itself to blame. God never intended that we should hide our unconfessed sins behind the confessed faults of a saint. Peter's contrary nature drove him to God. Unless ours does the same, Peter will have lived in vain for us. Anyway, we are glad Peter lived, and we are glad Christ found him. He is so much like so many of us, at least in his weaknesses. It only remains for us to learn also the secret of his strength.
